British jihadists return from Syria after being taught to kill by extremist Dutchman

The Muslim ex-soldier, who speaks fluent English, teaches weapons skills and warfare tips, such as how to cope in a fire-fight.

Worried security services are keeping tabs on the danger man, who calls himself “Chechclear” – a reference to a gruesome video posted online showing Chechen rebels beheading a Russian soldier.

MI6 and other Western intelligence agencies fear the ex-serviceman’s terror tips could be used on British soil as jihadists return from the Syria conflict.

The Dutchman, also known by his surname Yilmaz, has been in Syria for more than a year fighting against President Bashar Al-Assad’s government.

He carries out drills in a secret training camp while wearing his old Royal Netherlands Army uniform. Last year he appeared alongside two jihadists from London, Mohammed el-Araj, 23, and Choukri Ellekhlifi, 22, in an Instagram picture. Both Brits have since been killed.

The Foreign Office believes around 350 Brit jihadists have travelled to Syria to fight – but French president Francois Hollande reckons there could be up to 700.

Hollande made the claim following talks with David Cameron at RAF Brize Norton in Oxfordshire, although senior Whitehall sources later played down the figure.

So far up to 50 Brits are believed to have returned to the UK from fighting in Syria.

Last month there were 15 terror arrests in Britain linked to the conflict.

MI5 director-general Andrew Parker has said Syria is taking up a “growing proportion” of the agency’s work.

Last week Yilmaz, who is of Turkish descent, told Dutch TV he had been asked to train foreign fighters because of his military background.
